I keep getting rejected for entering the wrong AGI amount that’s on my 2020 return

Last year I filed with turbo tax and i filed married, so I went back on turbo tax and looked up the AGI . 
this year I am filing head of household I am not legally separated nor divorced am I have been paying for everything by myself.

I had no issues last year filing I didn’t amend my return and I didn’t file late. 
i entered the AGI correctly and it still keeps rejecting my return. Then I went and got my transcript off the IRS website and I tried that, it’s currently still pending. But if it get rejected again what is the problem? 
I have already tried to put 0. It is supposed to be 2020 and not 2019 correct? I just wanna make sure I’m doing everything the right way since filing by mail takes months (I assume)
